Activateable and deactivateable things

Certain things can be activated and deactivated using the appropriate specials. For monsters, this makes them not dormant and dormant respectively. A few other things will also do different things when activated or deactivated. These are:

Sparks (thing 9026): When activated, this thing emits some sparks.
Particle fountains (things 9027-9033): When activated, these things generate a fountain of particles. When deactivated, they don't.
Secret triggers (thing 9046): When activated, increments the number of secrets found and removes itself. The first parameter controls how noisy it is when it does this. When set to 0 or 1, this thing prints the message "A secret is revealed". When set to 0 or 2, it plays the secret sound. If any other values are used, this thing is silent.
